Which statement describes an advantage of dynamic routing?
A.
Dynamic routing provides redundant IP addresses for end-user devices, unlike static routing.
B.
Dynamic routing requires no initial user configuration, unlike static routing.
C.
Dynamic routing provides DNS services along with IP connectivity; static routing does not.
D.
Dynamic routing typically requires less time to implement than static routing in a large network.
Explanation:
Some of the general benefits of dynamic routing include lower administrative overhead, increased network availability, and greater network scalability.
Dynamic Routing
Static routing is ideal in small networks where only a few
routes exist or in networks where absolute control of routing is
necessary. However, static routing has certain drawbacks that
might make it cumbersome and hard to manage in large
environments where growth and change are constant. For
large networks or networks that change regularly, dynamic
routing might be the best option.
With dynamic routing, you simply configure the network interfaces to participate in a routing protocol. Devices running routing
protocols can dynamically learn routing information from each other. When a device adds or removes routing information for a
participating device, all other devices automatically update.
Benefits of Dynamic Routing
Dynamic routing resolves many of the limitations and drawbacks of static routing. Some of the general benefits of dynamic
routing include:
•Lower administrative overhead: The device learns routing information automatically, which eliminates the need for manual route definition;
•Increased network availability: During failure situations, dynamic routing can reroute traffic around the failure automatically (the ability to react to failures when they occur can provide increased network uptime); and
•Greater network scalability: The device easily manages network growth by dynamically learning routes and calculating the best paths through a network.
